BUILDING-BLOCKS.

To all whom it may concern:

Be it known that I, OLIVER BRUMBAUGH, a citizen of the United States, residing at Louisville, in the county of Staizk and State of Ohio, have invented certain new and us ful Improvements in Building-Blocks; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make andg use the same.

My invention relates to new and useful improvements in building blocks and ties therefor and more especially to that classadapted to, be used for constructing silos and my object is to provideblocks of bins Iclass which when properly assembled to- A gether, will form a circular wall.

A further object is to provide suitable gaskets and means to hold the same between the blocks toprevent leakage.

,through the wall and tying mechanism as seen on line 2-2, Fig. 1. Fig. 3 is a perspective view of two of theblocks, showing the manner of tying the same together. Fig. 4 is a vertical transverse sectional view on an enlarged scale as seen on line M, Fig. 2, showing the tie block in position and, Fig. 5 is a perspective view of the tie block removed.

Referring to the drawings in which simiv lar reference numerals designate correspond ing parts throughout the several views, 1 indicates the blocks, which may be constructed in the usual manner of suitable plastic material and is provided with openings 2 thereby leaving end walls 3 and providing in its length partition walls at, the

removal of the plastic material to form the openings 2, rendering the block light in weight, while the partitions 4 lend rlgidity to the block, and compensate for theremoval of the plastic material to form the openings.

Specification of Letters Patent.

Patented J an. 11, 1910.

The blocks are preferably curved so that I when they they ing the tiers of blocks one 'above the other,

the structure'may be erected-to any height are properly assembled together, will form a complete circle and byplac any suitable form of gasket 5 is" to be introduced between the meeting edges and ends of the blocks to render the joints 'water, and air tight, the ends of'the blocks being provided with semicircular channels '6 in which are ada' ted to enter ribs"? formed on the gaskets, said ribs holdin place between the blocks; Efter the blocks have been properly placedto ether, theends thereof are securely locke means of tie blocks 8, said blocks being channel shaped in cross section,I-the depending" flanges of which are adapted to engage the faces of theend ,walls 3 and it will e read-- ily seen that when the tieblocks are pro erl'y introduced over the meeting ends 0 J the blocks,

said blocks will "be securely -.lockcd togethe The lengths of the blocks 8- aro such as to sun ly fit inthe openings 2, the ends of the tielilock engaging the end walls of the middle opening of theflblock in the togetherby the gaskets in.

succeeding tier and in order to securely lockthe tie block in position, the upper end edges thereof are provided with grooves 9, which grooves cooperate with similar grooves 10' 1n the end walls of the central opening, the. I

grooves 10 being semi-circular, while the grooves 9 are but a segment of a circle, thereby leaving a mouthll between the endwall of the central opening and the; end wall of the block 8 through which any suitable form of plastic material 12 is introduced to fill the opening formed by the grooves 9 and 10 and after the plastic material 12 has been applied and becomes hardened, the tie blocks-will be permanently locked in posi' tion.

In constructing a silo or other =building, a tier of the blocks are properly positioned on a foundation and the ends thereof fastened together bymeans of the tie blocks 8, after which the gaskets are placed in position over the first tier and an additional tier of blocks placed upon the first tier, the second tier being so positioned 'that.the center of the blocks will be over the joints of the first tier and after the seeot'id tier is placedin position, the grocveafi and 10 are filled with plastic material while in a green state, a sufiicient quantity of the plastic material being placed over the faces of the tie block of the drawcan be Very Cheaply construetect and in View In thn manner it will be readily seen that a wnli form a perof the manner in which the blocks are tied Q together, said walls will be perfectly sc-hct 1 and rigid and-will withstand Si'OYmS and strong winds.

XVhat I claim is:

1. The combination with buiidi bioeks having end walls and opposed channels in S'Md end walls adapted to register with each I 1 two subsm'ibmg witnesses.

other when the blocks are pieced end to end of gaskets fitting between said building blocks and having ribs engaging said ehnni neis and means tying the blocks tegether,

2.
